EPS sandwich panel test report is a report issued after a comprehensive test of the performance of EPS sandwich panel, mainly including the following test items:
Appearance quality inspection: including dimensional measurement, surface quality inspection and uniformity inspection. Dimensional measurement checks whether the length, width and thickness of the sandwich panel meet the standard specifications, and checks whether its flatness and corners are neat; Surface quality inspection to check whether there are defects such as cracks, holes, stains or deformation on the surface of the sandwich panel; Uniformity check to observe the uniformity of the pore of the sandwich panel to ensure that its structure is dense and there is no obvious delamination.
Physical property testing: including density testing, thermal conductivity testing, compressive strength testing and water absorption testing. Density testing evaluates the material density of sandwich panels to ensure that their thermal insulation and mechanical properties meet standards; The thermal conductivity test evaluates the thermal insulation performance of the sandwich panel to ensure that it can effectively block heat conduction; Compressive strength testing evaluates the deformation ability of the sandwich panel when subjected to vertical pressure; The water absorption test evaluates the water absorption performance of the sandwich panel in a humid environment.
Safety testing: Ensure that EPS sandwich panels are non-toxic, odorless, radioactive and other harmful substances, and harmless to the human body and the environment.
Environmental protection testing: evaluate the environmental performance of EPS sandwich panels in the production, use and disposal process, including waste gas and wastewater discharge in the production process and recyclability after disposal.
Other performance testing: including dimensional stability testing, bending performance testing, compression performance testing, etc., to ensure that the sandwich panel will not be significantly deformed or warped during use.
